Onyx Liquid Embolic Systems - Prosthesis, internal, embolization, intravascular

Intended purpose

Embolization of intracranial aneurysms and lesions in the peripheral and neurovasculature including arteriovenous malformations and hypervascular tumours.

Functional description

Liquid Onyx is delivered through a DMSO primed microcatheter placed within a feeding pedicle of an AVM or an aneurysm. The DMSO priming volume separates Onyx from blood, saline or contrast media within the cathteter lumen that may cause early precipitation and catheter occlusion. Onyx material is injected at a slow rate. Solidification of the material begins immediately upon injection, beginning as a "skin" on the outside of the mass./ Total solidification occurs within minutes.
